[sallystudent]

Hi,

Which method is more efficent validation: PHP or Javascript??

Your thoughts would be greatly appreiciated??

Thanks

Javascript, of course, since you dont have to pass incorrect data to the server.

But you still have to do serverside validation anyway, since you cannot trust the client.

more efficient (mainly concernig file uploads): javascript
more effective and more secure: php

Thanks for this, but would you do both to be sure ??

thanks

depends on how heavy your serverload is...
if you don't have too many hints forget about the javascript...

But if we're not careful, we'll miss the point that Laserlight made. If your JS validation code doesn't add too much to the size of the HTML file being sent to the browser, and it's not too hard to do, use both.

Some designers are forgetting that some people still have rather slow connections. If you can save your user a page load by validating on the client side first, so much the better for these people. Remember the users....
